That seems a bit much to me. I guess it really depends on how often people go back and forth between tuners. For me, anything that I might watch I always hit record. So I might sometimes go back and forth between tuners when using my Roamio, but it is not the norm. I will say it would be nice if the Mini could do the same thing, but really so that the behavior of the Mini would be like a normal TiVo. They have already added more things that blur the lines between using a TiVo with a hard drive and a Mini. So if the closer the experience between the two is similar then the better.
